To create API routes in Expo Router, define server endpoints under the app/api directory using the +api.ts suffix. These files implement REST-like handlers for GET, POST, PUT, and DELETE requests securely on the server side.

Securing secrets and proxying external APIs in Expo is done by handling requests through EAS Hosting serverless endpoints. This keeps sensitive data and external service integrations on the server rather than embedding them in the client.

Yes, EAS Hosting supports serverless API routes for Expo Router by deploying them to Cloudflare Workers. You can manage environment variables, handle webhooks, and test locally using standard Expo tooling.

The best way to handle dynamic routing and HTTP methods in Expo API routes is by structuring files under app/api with the +api.ts suffix. This pattern supports dynamic routes, proper error handling, and specific handlers for GET, POST, PUT, DELETE, and OPTIONS requests.

Testing and deploying Expo Router API routes involves running them locally with the Expo development server and deploying to EAS Hosting. You manage environment variables and configure CORS and error handling within the serverless environment.

You should use Expo API routes to prevent exposing sensitive data in the client. This pattern provides a structured way to expose server-side logic, secure secrets, handle webhooks, and manage data flow safely without embedding keys in the app.
